Use Parallel Search in the Vercel AI SDK. Get started quickly by installing Parallel in the Vercel Agent Marketplace.

​
Vercel AI Gateway

Parallel Search is available as a built-in tool in Vercel AI Gateway. AI Gateway provides a unified API to access hundreds of models through a single endpoint, with built-in web search capabilities. The parallelSearch tool can be used with any model regardless of the model provider. When the model needs current information, it calls the tool and AI Gateway routes the request to Parallel’s Search API. 
import { gateway, streamText } from 'ai';

export async function POST(request: Request) {
  const { prompt } = await request.json();

  const result = streamText({
    model: 'anthropic/claude-sonnet-4.5', // Works with any model
    prompt,
    tools: {
      parallel_search: gateway.tools.parallelSearch(),
    },
  });

  return result.toDataStreamResponse();
}
You can configure additional parameters to tune the search behavior, such as maxResults, country, searchDomainFilter, and more. See the Parallel parameters documentation for the full list of options. For more details, see the Vercel AI Gateway Web Search documentation.
